On a more serious note, I suggest the g14 or the k4. Fighting with a tater chucking bird will rearrange how you look at air combat. The 109s have an amazing rate of climb and with some throttle work can lift their nose up and climb even when slow, something most other birds can't do as well. Furthermore, although it doesn't roll or turn like a spit16, you can 'out turn it' in two ways....
1) it makes a fairly extreme 'egg' shape when turned in the vertical. If you get it sub 100 mph at the top you can turn in a very short amount of space, and use the engine to roll it.
2) Out turning is not so much about 'exact' out turning but rather about creating a difference in e states. I can 'out turn' you if I can slow my plane down much faster than you and get to my corner speed before you can. Spits retain e much better.
